UNHED STAT realize PATENTOF COMBINED HOT PLATE AND LAUNDRY STOVE.

Application filed June 6,

pliance, and has for its aim the provision of such an appliance capable of use as a hot- 1 plate, which is adapted to be supported upon a table orthe like and is readily portable, and whichisalso capable of use as a laundry stove, being yfor this latterpurpose provided .with a detachable stand for supporting it a substantial distance above the floor as in the case of ordinary stoves. y

A further object of the invention is to .zo providea heating appliance of the character statedvwhich is of avery practical characterw y y y a y In the accompanyingdrawings wherein I have illustrated a preferred embodiment of" 2 my invention, Figure 1 is a front elevation of the improved heating appliance. Fig. 2 is a perspective View, of one of the end brackets and supporting members providing thelegs for the hot plate. Fig. 3 is a fragmentary horizontal section taken in the planeof line 3 of Fig. 5. Fig. 4 is a fragymentary transverse sectional view taken in the plane of line {l of Fig; 1. Fig. 5 is a fragmentary vertical longitudinal sectional view. Figs. 6 and 7 are detached perspective views of the'burner supporting barand one of the tray supporting members for the usual catch or drip pan. a y

The device comprises generally a rectangular frame 8 having at each end a pair of supporting members or brackets 9 and an extension support or stand comprising a' plurality oflegs 10 connected at their lower ends by means of a fianged plate 11 and detachably securedat their upper ends to said end members.

, The stove frame S is preferably made from sheetv metal bent; into channel form, and the end members are also formed of sheet anetal and each comprises an end wall 9. and two sidewalls 9 pr'oviding a pair of depending angular portions 12 constituting supporting members for the frame. 1

The legs 10 of the supportingstand for i the stove are made angular in form, with their upper endsconformmg to the shape of the angular portions 1210f thesupport ing members 9; and the upper portions of the legs are fastened to the angular portions 12 by means of bolts 17 entered through registering apertures provided in the legs and in themember 9 at vertically Preferably the legs are,

spaced intervals. arranged to fit over the outer corners of the supporting members, with their upper ends abutting the underside of the frame 8. As shown at18 in Fig. 3 the opposite edges of the legs 10. are bent inwardly and back upon themselves to form stifiening means for the legs.

The plate;11-,which servesto connect the lower ends of the legs together. is formed froma single sheet of metal having downturned flanges which are/secured to the walls J of the'legs by means of bolts 19. The plate 11 thus constitutesa bracing means for the stand. 1 I a A suitable number of burners 20' (two he ing herein shown) aremounted beneath the usual grids 21, the latter being removably supported by the frame 8 in the usual way. The means for supporting the burners ,may

. comprise a channel bar22 extending longi tudinally of the frame and having its opposite ends fastened in the end members 9.

, Such fastening for the'ends of the bar may be of anysuitable character, but preferably,

is of such a nature as to render the bar removable at will. One form ofinea ns for this purpose comprises a bracket 22 secured upon the inner sides of the supporting members 9 and comprising an inwardly extending portion 23 and a downturned portion 24. The portion 24; is notched as at 25to' receive the end of the bar 22, while the latter is provided with laterally extending lugs 26 forengagement with the depending portion-24: of the bracket 22 whereby detachably to, secure the bar in position upon 1 said bracket. y y A gasmanifold27 is suitably mounted at the forward side of the stove by means of brackets 28, secured at theininner ends to the under side of the frame 8 as by means of bolts 29. One end of said manifold is provided with a fitting for the reception of a flexible gas conductor in a well members or brackets 33 secured to the supportingmembers and adapted to removably support the pan 32. As shown in said'flgures, each of said brackets 33 is formed from a single sheet of metal to provide a fmain or top plate 34 having downturned end flanges 35'and side flanges 36 and 37, The downturned side flanges 35 and the outer flange 36 arerespectively secured to the opposite side walls of the end members 9and the end wall thereof. The side flange '37 on the inner edge carries a horizontal inwardly extending flange 38 which provides a'support for the pan 32, and the ends of said flange 38 are upturned as at 39 to provide retaining lugs for the pan. It will be 1 evident that by this construction the upper edges of the edge flanges of the pan lie substantially flush with the plates 34 of the supporting members. A

It will be seen that the appliance is readily adapted for use as a hot plate, the supporting stand consisting of the legs 10 and the connecting'plate' 11 being for this purpose removed. Thus the angular portions 12 constitute legs for supporting the hot plate upon the table or other support. At the same time the device is readily convertible into a stove, which is especially adapted for use as alaundry stove, by attaching the stand to the angular portions 12 of the'supporting members. The construction isof an exceedingly simple character and the stove in either form is exceedingly rigid:

While I have herein illustrated and described the invention with reference to a single embodiment, it will be understood "that various changesin form, construction and arrangement may be made without de-.

parting from the spirit and scope of the invention as expressed in the appended claims.
